Question

Solve for r: 3r+2-r=-4

Answer 1

r = -3

Explanation:

3r + 2 - r = -4 (Given)

2r + 2 = -4 (Simplify)

2r + 2 - 2 = -4 - 2 (Subtract 2 on both sides)

2r = -6 (Simplify)

2r/2 = -6/2 (Divide 2 on both sides)

r = -3 (Simplify)

Answer 2

r = -3

Explanation:

3r + 2 - r = -4

2r + 2 = -4

2r = -6

r = -3
